Product Overview

The Pentair BioShield UV System is a high-output ultraviolet water-treatment system designed to improve swimming-pool water quality by helping reduce combined chloramines and the odors and irritation commonly associated with them. This 80-watt model is designed for applications requiring flow rates up to 45 GPM at the specified UV dose. Its low-pressure, high-output UV lamp delivers efficient UV-C treatment while the durable polymer vessel is engineered specifically for pool environments.

The BioShield works alongside the pool’s primary sanitation system rather than replacing chlorine or salt chlorination, making it an effective supplemental water-quality solution for residential pools and other appropriately sized aquatic applications.

Ideal For

• Residential pools requiring supplemental UV water treatment

• Indoor or outdoor pools where chloramine control is important

• Pools using chlorine or Pentair IntelliChlor salt chlorination

• New equipment-pad installations or water-treatment upgrades

Key Features

• High-output 80W UV lamp with approximately 27 watts of UV-C output

• Rated for 45 GPM at a 40 mJ/cm² UV dose

• Dual-voltage 115/230V electrical compatibility

• UV-resistant, high-density polymer vessel designed for pool environments

• Visual lamp-status indication for easier system monitoring

• Automatic low-flow shutoff protection helps protect the unit and extend lamp life

• Designed to accommodate 2", 2.5", or 3" plumbing connections

• Less than 0.5 PSI pressure loss under specified operating conditions

Benefits

• Helps reduce combined chloramines that can contribute to strong chemical odors and swimmer discomfort

• Adds another layer of water treatment without replacing the pool’s normal sanitizer

• Low hydraulic restriction helps maintain efficient circulation-system performance

• High-output lamp technology provides substantial UV-C output from an 80W system

• Compatible with Pentair automation and water-treatment equipment for an integrated equipment-pad installation

Compatibility

The BioShield 522636 can be incorporated into appropriately sized pool circulation systems and used alongside conventional chlorine or salt-chlorine sanitation.

Pentair identifies the BioShield family as compatible with IntelliTouch and EasyTouch automation systems as well as IntelliChlor Plus, IntelliChlor LT, and IntelliChem equipment.

Proper sizing should be based on pool volume, circulation time, required UV dose, and actual system flow—not pump horsepower alone.

Installation & Upgrade Context

The BioShield is installed in the pool circulation plumbing so filtered water passes through the UV treatment chamber. The system requires appropriate plumbing space, electrical service, flow verification, and access for future lamp and quartz-sleeve maintenance.

Because the system combines electrical components with pressurized pool plumbing, installation by a qualified pool professional or electrician is recommended. Always verify available equipment-pad space and system flow before ordering.

Confirm Before Ordering

Before purchasing, confirm:

• Required system flow rate

• Available installation space

• 115V or 230V electrical supply

• Existing plumbing diameter and layout

• Pool volume and desired turnover rate

• Compatibility with any existing automation or chemical-control equipment

Specifications

Customer Q&A

Does the BioShield 522636 replace chlorine or a salt system?
No. BioShield is supplemental UV water treatment and should be used alongside the pool’s normal sanitation system.

What size pool can the 522636 handle?
Sizing depends on both pool volume and daily circulation time. The 45 GPM rating should be compared with the pool’s actual flow rate and desired turnover schedule.

Can it work with Pentair automation?
Yes. Pentair lists the BioShield system as compatible with IntelliTouch and EasyTouch control systems and with selected IntelliChlor and IntelliChem equipment.

What replacement lamp does the 80W BioShield use?
Pentair identifies replacement lamp 523036 for the current 80W high-output BioShield configuration. Always confirm the existing system revision before ordering replacement components.
